This indicates that g.region fails (as you have seen below).

It comes from G__read_Cell_head_array() which is a function
to read the raster map header.

I suspect that the "all_cdec_costd_mincost_1" raster map [header]
is corrupted. It is an ASCII file in the mapset's cellhd/ directory, maybe
you can fix it. Reason for corruption might be
- disk temporarily full
- GRASS database on NFS/other shared directory disappeared due to
  network problems.

Best will be to recreate the corrupted map.
